Wanted: a standard for virtual patent marking

How can a standard for virtual patent marking (VPM) be developed to enhance its adoption and functionality?

We care because virtual patent marking has emerged as a pivotal tool for patent owners to notify the public of patent rights without physically marking products. However, confusion surrounding the practicalities of VPM implementation, such as the format of relevant webpages and their ongoing accessibility, has hindered widespread adoption. Establishing a clear standard for VPM formatting could facilitate compliance, reduce legal ambiguities, and ultimately enhance the protection of intellectual property rights across jurisdictions, benefiting both patentees and potential infringers.

We conducted a comprehensive review of the current state of virtual patent marking webpages, analyzing data obtained from the IPRoduct project to assess their functionality. Specifically, we examined a random sample of VPM pages to identify accessibility issues and the extent of product–patent associations, establishing a probability of VPM validity based on the age of the pages. The study involved an assessment of about 50 VPM pages for redirects and their associated functionalities.

We found that the probability for any given VPM page being functional decreases with time, from about 27% for pages less than one year old to over 4% for those older than three years. Furthermore, we found that around 24% of self-declared VPM pages do not meet critical requirements for functionality, emphasizing the need for clearer standards. Ultimately, we propose a set of guidelines for effective VPM implementation to ensure compliance with existing legal frameworks.

• Sample of virtual patent marking webpages from the IPRoduct database, including those indexed over a three-year period

• We assume that patentees can maintain continuity and consistency of VPM webpages
• We assume that existing legal frameworks can accommodate the proposed guidelines for VPMs
• We assume that the accessibility and functionality of VPMs can be effectively assessed through a sample analysis
